The Kline-Fogleman Airfoil is often used to make wings of different designs. They are often reffered to as KFm.... 1,2,3 etc.

If you have ever wondered what people are talking about when they discuss which KFm wing design there going to use heres what they are talking about :

Its amazing how much you can effect your platform through incorperating a KFm design to suit the flying. Weight and overall design of you platform to gain certain flying advantages if the right wing design is used.

I built the 'Divinity' over on RCG and for 2 evenings work, from a sheet of Depron to in the sky, the KF airfoil is as easy as it gets using the KFm4 airfoil.

In there is my posts and it was resized slightly to get it all from a 1 metre x 700mm sheet of depron (cost = less than a fiver).
